Timeline of History

John Venn dies in Cambridge, England. John Venn played a critical role in the development of modern logic by creating a system for diagramming that can test the validity of categorical syllogisms.

Called Venn Diagrams, they are very useful for ensuring that an argument is valid. Venn diagrams use circles to represent sets, with the position and overlap of the circles showing the relationships between the sets.
